An efficient continuous photochemical process is presented that delivers a series of novel γ-aminopropylsulfones via a tetrabutylammonium decatungstate (TBADT) catalysed HAT-process. Crucial to this success is the exploitation of a new high-power LED emitting at 365 nm that was found to be superior to an alternative medium-pressure Hg lamp. The resulting flow process enabled the scale-up of this transformation
提出了一种高效的连续光化学工艺,该工艺通过十钨酸四丁基铵 (TBADT) 催化的 HAT 工艺提供一系列新型 γ-氨基丙基砜。这一成功的关键是开发了一种新的 365 nm 高功率 LED,该 LED 被发现优于替代的中压汞灯。由此产生的流动过程使这种转化的规模扩大,达到 20 mmol h -1的吞吐量底物浓度高达 500 mM。此外,评估了这种转化的底物范围,证明了不同的胺取代基以及砜部分旁边的烷基附加物的直接结合。预计这种方法将允许在未来进一步开发这些代表性不足的 γ-氨基丙基砜支架。

[Object]
A novel and excellent method for preventing or treating rejection in the transplantation of various organs, allergy diseases, autoimmune diseases, hematologic tumor, or the like, based on a PI3Kδ-selective inhibitory action and/or an IL-2 production inhibitory action, and/or a B cell proliferation inhibitory action (including an activation inhibitory action), is provided
[Means for Solution]
It was found that a 3-substituted triazine or 3-substituted pyrimidine derivative exhibits a PI3Kδ-selective inhibitory action, and/or an IL-2 production inhibitory action, and/or a B cell proliferation inhibitory action (including an activation inhibitory action), and can be an agent for preventing or treating rejection in the transplantation of various organs, allergy diseases (asthma, atopic dermatitis, etc.), autoimmune diseases (rheumatoid arthritis, psoriasis, ulcerative colitis, Crohn's disease, systemic lupus erythematosus, etc.), hematologic tumor (leukemia etc.), or the like, thereby completing the present invention.
